Parameters
|
|
-----------
|
|
max_messages : Optional[:class:`int`]
|
|
The maximum number of messages to store in the internal message cache.
|
|
This defaults to 5000. Passing in `None` or a value less than 100
|
|
will use the default instead of the passed in value.
|
|
loop : Optional[event loop]
|
|
The `event loop`_ to use for asynchronous operations. Defaults to ``None``,
|
|
in which case the default event loop is used via ``asyncio.get_event_loop()``.
|
|
connector : aiohttp.BaseConnector
|
|
The `connector`_ to use for connection pooling.
|
|
proxy : Optional[:class:`str`]
|
|
Proxy URL.
|
|
proxy_auth : Optional[aiohttp.BasicAuth]
|
|
An object that represents proxy HTTP Basic Authorization.
|
|
shard_id : Optional[:class:`int`]
|
|
Integer starting at 0 and less than shard_count.
|
|
shard_count : Optional[:class:`int`]
|
|
The total number of shards.
|
|
fetch_offline_members: :class:`bool`
|
|
Indicates if :func:`on_ready` should be delayed to fetch all offline
|
|
members from the guilds the bot belongs to. If this is ``False``\, then
|
|
no offline members are received and :meth:`request_offline_members`
|
|
must be used to fetch the offline members of the guild.
|
|
status: Optional[:class:`Status`]
|
|
A status to start your presence with upon logging on to Discord.
|
|
activity: Optional[Union[:class:`Activity`, :class:`Game`, :class:`Streaming`]]
|
|
An activity to start your presence with upon logging on to Discord.
|
|
heartbeat_timeout: :class:`float`
|
|
The maximum numbers of seconds before timing out and restarting the
|
|
WebSocket in the case of not receiving a HEARTBEAT_ACK. Useful if
|
|
processing the initial packets take too long to the point of disconnecting
|
|
you. The default timeout is 60 seconds.
